NEW YORK, March 10 (Reuters) - U.S. stocks fell 1 percent on
Tuesday, with major indexes dropping in a broad decline and
turning negative for the year amid continued strength in the
U.S. dollar.

Concerns over Greece's debt talks added to the day's
weakness, which took the S&P 500 below its 50-day moving
average, a sign of weak near-term momentum.

The U.S. Dollar index rose 0.7 percent and is on
track for its fourth rise of the past five sessions, up 3
percent over that period. The euro fell 0.9 percent
against the dollar to nearly a 12-year low.

"There's some concern about what impact this will have on
corporate earnings going forward, especially for the big
multi-national companies," said Nicholas Colas, chief market
strategist at the ConvergEx Group in New York.
